I have a geometry with multiple body parts, whenever I choose "share" option in SpaceClaim, Ansys mesher fails to mesh my geometry with "multizone" method and I'm not satisfied with unstructured mesh using other methods. However, when I set my Component in "grouped" mode in SpaceClaim, I have more control on edge sizing and a good structure mesh happens with multizone method.

Would I face a problem in future if I do not choose "share" option? Would I get correct results from my analysis?

I'm also attaching a picture of my geometry

Thanks for your attention.

Hi @sarbakhshian
Share Topology (Share Topology (ansys.com)) is used when bodies are grouped into multi-body parts and the solid(s) and surface(s) are touching or intersecting.If the bodies are Shared then the nodes will also be shared and thus the mesh.
When "Group" (Groups (ansys.com)) is used the multi parts are saved as individual parts and no node is shared between them. Thus Contacts will come up during analysis.
Both the approaches are suited for different conditions and the correctness of your analysis depends on your problem statement.
Please refer to this to get a clear idea - Contact or Shared Topology ÔÇö Ansys Learning Forum
